Abstract

The gas cooker top has gas burners each with a flame monitoring sensor which shuts off a main valve in the main gas line if the flame of at the least the first burner is extinguished. The closing of the main valve is registered by an indicator (21). After the closing of the main valve the indicator additionally indicates the second gas burner provided that its adjustment element located in a gas line split off from the main gas line is in an open position. An independent claim is included for a method for the indicating of a first and a second gas burner on a gas cooker top.

Die Funktionsweise des Gaskochfeldes ist anhand des Blockschaltbilds der Figur 2 beschrieben. Aus Gründen der Übersichtlichkeit ist das Blockschaltbild der Figur 2 auf den Gasbrenner 1 mit dem zugeordneten Bedienknebel 13 sowie der Störanzeige 21 beschränkt. Die weiteren Gasbrenner 3, 5, 7 sind in entsprechender Weise in dem Gaskochfeld verschaltet. Für eine Flammenüberwachung ist dem Gasbrenner 1 gemäß der Figur 2 eine Ionisationselektrode 29 zugeordnet, mit der ein Vorhandensein einer Flamme des Brenners 1 erfasst wird. Mittels der Flamme kann ein Spalt zwischen der Flammenionisationselektrode 29 und dem Gasbrenner 1 elektrisch überbrückt werden, wodurch ein entsprechendes Signal von der Ionisationselektrode 29 über eine Signalleitung 31 zu einer elektronischen Steuereinrichtung 33 geleitet wird. Die elektrische Steuereinrichtung 33 ist über eine weitere Signalleitung 35 mit einem Hauptventil 37 in Verbindung. Das Hauptventil 37 ist in einer Hauptgasleitung 39 angeordnet, die an ein Gasversorgungsnetz gekoppelt ist. Ausgangsseitig ist das Hauptventil 37 mit einem Verteilerrohr 41 verbunden, von dem Teilgasleitungen 42 jeweils zu den Gasbrennern 1, 3, 5, 7 führen.The operation of the gas cooktop is based on the block diagram of Figure 2 described. For clarity, the block diagram of Figure 2 is on the gas burner 1 with the associated control knob 13 and the fault indicator 21st limited. The other gas burner 3, 5, 7 are in a corresponding manner in the Gas hob interconnected. For a flame monitoring is the gas burner 1 according to 2 an ionization electrode 29 associated with the presence of a Flame of the burner 1 is detected. By means of the flame can be a gap between the Flame ionization electrode 29 and the gas burner 1 are electrically bridged, whereby a corresponding signal from the ionization electrode 29 via a Signal line 31 is passed to an electronic control device 33. The electric Control device 33 is connected via a further signal line 35 with a main valve 37 in Connection. The main valve 37 is arranged in a main gas line 39 which is connected to a Gas supply network is coupled. On the output side, the main valve 37 with a Distributor tube 41 is connected, from the partial gas lines 42 respectively to the gas burners 1, 3, 5, 7 lead.

In der Figur 2 ist lediglich der Gasweg zu dem Gasbrenner 1 vollständig dargestellt. In der zu dem Gasbrenner 1 führenden Teilgasleitung 42 ist ein Gashahn 45 angeordnet, mit dem ein Gasmengenstrom zum Gasbrenner 1 eingestellt wird. Dessen Schaltwelle 47 ist über ein Schaltgestänge 49 mit dem Drehknebel 13 verbunden. Zwischen dem Schaltgestänge 49 und dem Drehknebel 13 ist ein Signalgeber 51 geschaltet. Der Signalgeber 51 erfasst eine Drehposition des Drehknebels 13 und gibt diese über eine Leitung 53 an die elektronische Steuereinrichtung 33. In entsprechender Weise werden die Drehpositionen der weiteren Bedienknebel 15, 17, 19 über die mit gestrichelter Linie angedeuteten Signalleitungen zur elektronischen Steuereinrichtung 33 geleitet. Über die elektronische Steuereinrichtung 33 ist die Störanzeige 21 des Gasbrenners 1 ansteuerbar.In FIG. 2, only the gas path to the gas burner 1 is shown completely. In the to the gas burner 1 leading partial gas line 42 is a gas tap 45 is arranged, with a gas flow rate is set to the gas burner 1. Its selector shaft 47 is connected via a shift linkage 49 with the rotary knob 13. Between the Shift linkage 49 and the rotary knob 13, a signal generator 51 is connected. Of the Signal generator 51 detects a rotational position of the rotary knob 13 and outputs this via a Line 53 to the electronic control device 33. In a corresponding manner the rotational positions of the other control knob 15, 17, 19 over the dashed line indicated signal lines to the electronic control device 33 passed. About the Electronic control device 33 is the fault indicator 21 of the gas burner. 1 controllable.

Zum Start eines Brennerbetriebs wird gemäß der Figur 2 der Bedienknebel 13 zunächst aus seiner Nullstellung gedreht, in der sich der Gashahn 45 in einer Schließstellung befindet. Diese Anfangsdrehung wird durch den Signalgeber 51 erfasst, der ein entsprechendes Signal an die elektronische Steuereinrichtung 33 leitet. Daraufhin öffnet die elektronische Steuereinrichtung 33 das normalerweise geschlossene Hauptventil 37, so dass über die Hauptgasleitung 39 und die Teilgasleitung 42 ein Gasmengenstrom dem Gasbrenner 1 zugeführt wird. Gleichzeitig steuert die elektronische Steuereinrichtung 33 die Ionisationselektrode 29 an, um den Gasbrenner 1 zu zünden. Eine Einstellung des Gasmengenstroms zum Gasbrenner 1 erfolgt mittels des Gashahns 45. Dessen Strömungsquerschnitt kann über den Bedienknebel 13 entsprechend verändert werden. To start a burner operation, the control knob 13 is shown in FIG. 2 first rotated from its zero position, in which the gas cock 45 in a closed position located. This initial rotation is detected by the signal generator 51, the one corresponding signal to the electronic control device 33 passes. Thereupon opens the electronic control device 33 the normally closed main valve 37, so that via the main gas line 39 and the partial gas line 42, a gas flow rate the Gas burner 1 is supplied. At the same time, the electronic control device 33 controls the ionization electrode 29 to ignite the gas burner 1. A setting of the Gas flow rate to the gas burner 1 by means of the gas tap 45th Whose Flow cross-section can be changed accordingly via the control knob 13.

Während des Betriebes des Gasbrenners 1 ist die LED-Anzeige 21 dauerhaft eingeschaltet.During operation of the gas burner 1, the LED display 21 is permanent switched on.

In den Figuren 3a bis 3c ist die Bedienleiste 11 mit den Bedienknebeln 13 bis 19 sowie den Anzeigen 21 bis 27 dargestellt. Gemäß der Figur 3a sind die drei Gasbrenner 1, 3, 5 in Betrieb. Demgemäß sind die zugeordneten Bedienknebel 13, 15, 17 aus ihrer Nullstellung gedreht. Die zugeordneten LED-Anzeigen 21 sind dauerhaft erleuchtet, so dass für dem Benutzer klar ersichtlich ist, dass die Gasbrenner 1, 3, 5 in Betrieb sind. Der Bedienknebel 19 des Gasbrenners 7 ist dagegen in seiner Nullstellung und seine zugeordnete LED-Anzeige 21 ist ausgeschaltet. D.h., dass für den Benutzer klar ersichtlich ist, dass der Gasbrenner 7 außer Betrieb ist.In the figures 3a to 3c, the control bar 11 with the control knobs 13 to 19 and the displays 21 to 27 shown. According to FIG. 3 a, the three gas burners 1, 3, 5 in operation. Accordingly, the associated control knob 13, 15, 17 from their Zero position turned. The associated LED displays 21 are permanently lit, so that it is clear to the user that the gas burners 1, 3, 5 are in operation. Of the Control knob 19 of the gas burner 7, however, is in its zero position and its associated LED display 21 is turned off. That is, clear to the user it can be seen that the gas burner 7 is out of operation.

In den Figuren 3b und 3c wird von dem Fall ausgegangen, dass die Flamme am Gasbrenner 1 fehlerhaft während des Brennerbetriebs erlischt. Ein solches Erlöschen der Flamme erfolgt bspw. aufgrund von Garflüssigkeit, die auf den Brenner 1 tropft. Ein solches Erlöschen der Flamme wird durch zugeordnete Flammenionisationselektrode 29 erfasst, so dass ein entsprechendes Signal an die elektronische Steuereinrichtung 33 geleitet wird. Die elektronische Steuereinrichtung 33 steuert die Flammenionisationselektrode 29 an, damit der Gasbrenner 1 für ein wiederentzündet wird. Sofern eine solche Wiederentzündung des Gasbrenners 1 erfolglos bleibt, schließt die elektronische Steuereinrichtung 33 das Hauptventil 37. Dadurch ist die Gaszufuhr zu den allen Gasbrennern der Gaskochstelle unterbrochen. Gleichzeitig steuert die elektronische Steuereinrichtung 33 die LED-Anzeigen aller Gasbrenner 1, 3, 5 an, deren Gashähne 45 sich nach dem Schließen des Hauptventils 37 noch in einer Offenstellung befinden. Vorliegend steuert die Steuereinrichtung 33 die LED-Anzeigen 21, 23, 25 an. Die LED-Anzeigen 21, 23, 25 beginnen daher zu blinken, wie in der Figur 3b angedeutet sein soll. Dadurch erhält der Benutzer einen Hinweis darauf, welche Gasbrenner bis zum Erlöschen der Flamme des Gasbrenners 1 in Betrieb gewesen sind bzw. die Gashähne 45 welcher Gasbrenner noch offen sind.In the figures 3b and 3c is assumed from the case that the flame on Gas burner 1 faulty during burner operation goes out. Such extinction of the Flame takes place, for example, due to cooking liquid, which drips onto the burner 1. One such extinction of the flame is caused by associated flame ionization electrode 29 detected, so that a corresponding signal to the electronic control device 33rd is directed. The electronic control device 33 controls the Flame ionization electrode 29, so that the gas burner 1 for a reignited becomes. If such a reignition of the gas burner 1 is unsuccessful, closes the electronic control device 33, the main valve 37. This is the gas supply too interrupted all the gas burners of the gas cooker. At the same time, the electronic control device 33, the LED displays all gas burners 1, 3, 5, whose Gas taps 45 are still in an open position after closing the main valve 37 are located. In the present case, the control device 33 activates the LED displays 21, 23, 25. The LED displays 21, 23, 25 therefore start to flash, as indicated in FIG. 3b should be. This will give the user an indication of which gas burners are on until Extinguish the flame of the gas burner 1 have been in operation or the gas taps 45 which gas burners are still open.

Damit der Benutzer das Gaskochfeld erneut in Betrieb setzen kann, müssen wegen Sicherheitsgründen zunächst die noch offenen Gashähne 45 in ihre Schließstellung zurückgestellt werden. Solange dies nicht der Fall ist, blinken die den Gasbrennern 1, 3, 5 zugeordneten LED-Anzeigen 21 bis 25 weiter. Nachdem alle Gashähne 45 mittels der Bedienknebel 13, 15, 17 in ihre Schließstellung gebracht sind, blinkt nur noch die LED-Anzeige 21, die dem Gasbrenner 1 zugeordnet ist, wie es in der Figur 3c dargestellt ist. Hierdurch erhält der Benutzer einen Hinweis darauf, dass am Gasbrenner 1 die Flamme ein fehlerhaft erlöscht ist.So that the user can put the gas hob again into operation, must because For safety reasons, first the still open gas taps 45 in their closed position be reset. As long as this is not the case, the gas burners 1, 3, 5 flash associated LED displays 21 to 25 on. After all gas taps 45 by means of Control knob 13, 15, 17 are brought into their closed position, only the LED indicator flashes 21, which is associated with the gas burner 1, as shown in Figure 3c. This gives the user an indication that the gas burner 1, the flame a faulty is extinguished.

Wenn alle Gashähne 45 wieder in ihrer Schließstellung sind, wie in der Figur 3c der Fall ist, können die verbleibenden funktionsfähigen Gasbrenner 1, 5, 7 des Gaskochfeldes erneut in Betrieb genommen werden. Das in der Figur 3c dargestellte Blinken der LED-Anzeige 23 des Gasbrenners 3 kann zeitlich begrenzt sein.When all gas taps 45 are again in their closed position, as in the figure 3c of the case is, the remaining functioning gas burner 1, 5, 7 of the gas hob be put into operation again. The flashing of the LED display shown in FIG. 3c 23 of the gas burner 3 may be limited in time.
